Long term investing works well, but it doesn't always work for each individual stock. We really hate to see fellow investors lose their hard-earned money. Spare a thought for those who held OFILM Group Co., Ltd. (SZSE:002456) for five whole years - as the share price tanked 74%. And we doubt long term believers are the only worried holders, since the stock price has declined 30% over the last twelve months.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

Check out our latest analysis for OFILM Group

OFILM Group wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Over half a decade OFILM Group reduced its trailing twelve month revenue by 8.3% for each year. That's not what investors generally want to see. If a business loses money, you want it to grow, so no surprises that the share price has dropped 12% each year in that time. It takes a certain kind of mental fortitude (or recklessness) to buy shares in a company that loses money and doesn't grow revenue. That is not really what the successful investors we know aim for.

A Different Perspective

While the broader market lost about 5.4% in the twelve months, OFILM Group shareholders did even worse, losing 30%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 12% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand OFILM Group better, we need to consider many other factors.
